Reporting from Washington -- President Obama's leading counterterrorism advisor said this morning that human error  but not turf battles between federal intelligence officials  allowed an al Qaeda-trained operative to carry out an attempt to bomb a Detroit-bound airplane on Christmas Day.

Deputy National Security Advisor John O. Brennan, in appearances on several Sunday morning television news programs, also said there was "no smoking gun" of intelligence gathered by American officials that would have directly suggested the Flight 253 attack by Nigerian Umar Farouk Abdulmutallab was imminent.

"There was no piece of intelligence that said, 'this guy's a terrorist. He's going to get on a plane'," Brennan said. Later, he added: "It was the failure to integrate and piece together those bits and pieces of information."

Brennan is leading the Obama-ordered review of intelligence-gathering and watchlisting efforts, which failed to block Abdulmutallab from boarding the plane despite several red flags known to U.S. officials  including a personal warning from Abdulmutallab's father that the young man was displaying extremist tendencies.

Brennan said the review had so far yielded no evidence that various agencies withheld that intelligence from one another, as was the case with rival agencies in the lead-up to the Sept. 11, 2001, terrorist attacks.

"There is no indication whatsoever that any agency or department was not trying to share information" on Abdulmutallab, Brennan said. "There (were) some lapses. There was some human error."

Brennan defended the sophistication of the government's anti-terror system, after one interviewer questioned if it could stack up to Facebook, the popular Internet social networking site.

More broadly, he defended the Obama administration's anti-terror efforts, including its decision to charge Abdulmutallab in criminal court and its plans to close the Guantanamo Bay detention facility. He said Obama would still consider returning ex-Guantanamo prisoners to Yemen.

He explained the decision to close the U.S. embassy in Yemen today by saying intelligence officials believe there is threat of another al Qaeda attack there.

And he said there was evidence that al Qaeda is training new operatives in Yemen to send "to the West" for possible attacks.

"We are doing everything possible to scour all the intelligence to see if there is another Abdulmutallab out there," Brennan said.Brennan spoke on " Fox News Sunday," CNN's "State of the Union," ABC's "This Week" and NBC's "Meet the Press."

In several instances, he was followed by congressional Republicans who criticized his comments and the administration's national security policies.

The top Republican on the Senate Select Committee on Intelligence, Sen. Christopher Bond of Missouri, said on Fox that he was "very disturbed" that Obama would consider releasing Guantanamo detainees to any other country, in light of reports that several al Qaeda leaders in Yemen are former Guantanamo prisoners released during the Bush administration.

"If we don't stop the practice of releasing Gitmo detainees, to Yemen or to other countries we're asking for even more trouble," Bond said.On CNN.

Sen. Jim DeMint (R-S.C.), said Brennan "seems to have a hard time saying (the bombing attempt) was an act of terror.""This threat is real," DeMint said, "and we need to make some very real changes."

Other Republicans were more measured. On CNN, former New Jersey Gov. Thomas Kean, the chairman of the 9/11 Commission, praised Obama's reaction to the Flight 253 attack. But he said it was clear that until Christmas, the administration was "distracted" by health care, the economy, global warming and other issues and not "focused as it should be on terrorism."

In his interviews, Brennan rebutted one Republican charge repeatedly: former Vice President Dick Cheney's accusation last week that Obama is "pretending" that the United States is not at war with terrorists.

Cheney is either "willfully mischaracterizing" Obama's position, Brennan said, or "ignorant of the facts." The administration, he said, is "determined to destroy al Qaeda, whether it's in Pakistan, Afghanistan or in Yemen. We will get there."

When a particularly lethal outbreak of a never-before-seen virus began spreading around Saudi Arabia in 2012, a few researchers in Maryland and around the United States already had a jump on the investigation into its origins.

A program launched in 2011 by the state's largest health insurer to better coordinate patient care has slowed its overall pace of spending, avoiding millions in costs for the company and those it insures, CareFirst BlueCross BlueShield reported Thursday.

An experimental Ebola vaccine tested on thousands of people in Guinea seems to work and might help shut down the waning epidemic in West Africa, according to interim results from a study published Friday.
